[0045] Traditional solar water heaters mainly heat the water through solar energy systems. The heating method is single and the heating effect is poor on rainy days, resulting in the water temperature not meeting people's needs.

[0046] To this end, the embodiment of the present application provides a solar water heating installation system, which can improve the problem of the single heating method of traditional solar water heaters, and can realize automatic control, which is conducive to saving energy consumption.

[0047] In order to make the objectives, technical solutions and advantages of the present application more clear, they are described in detail below with reference to specific drawings and embodiments.

[0048] refer to Figure 1 The solar water heating installation system provided in the embodiment of the present application includes: a first circulation pipeline 1, a second circulation pipeline 2, a first insulated water tank 3, a second insulated water tank 4, a first circulation pump 5, a second circulation pump 6, a solar collector 7, an air source heat pump 8, a first solenoid valve 9 and a second solenoid valve 10. The first insulated water tank 3, the first circulation pump 5 and the solar collector 7 are connected in series to the first circulation pipeline 1. The first circulation pump 5 is used to circulate the water in the first insulated water tank 3 in the first circulation pipeline 1. The solar collector 7 is used to heat the water in the first insulated water tank 3 using solar energy. The second insulated water tank 4, the second circulation pump 6 and the air source heat pump 8 are connected in series to the second circulation pipeline 2. The second circulation pump 6 is used to circulate the water in the second insulated water tank 4 in the second circulation pipeline 2. The air source heat pump 8 is used to heat the water in the second insulated water tank 4 using air energy. The first solenoid valve 9 is arranged at the hot water outlet of the first insulated water tank 3, and is used to open / close the hot water outlet of the first insulated water tank 3. The second solenoid valve 10 is disposed at the hot water outlet of the second insulated water tank 4 and is used to open / close the hot water outlet of the second insulated water tank 4 .

[0049] The first insulated water tank 3 , the first circulation pump 5 , the solar collector 7 , the first circulation pipeline 1 and the first solenoid valve 9 constitute a first hot water system, which can collect solar energy and use it to heat the water in the first insulated water tank 3 .

[0050] The second insulated water tank 4 , the second circulation pump 6 , the air source heat pump 8 , the second circulation pipeline 2 and the second solenoid valve 10 constitute a second hot water system, which can absorb heat from the air and use it to heat the water in the second insulated water tank 4 .

[0051] According to the above scheme, the solar water heating installation system can realize two water heating methods: solar energy and air energy, which can improve the problem of single heating method of traditional solar water heaters.

[0052] During use, the solar water heating system can choose to be supplied with hot water by the first hot water system or the second hot water system. Specifically, when the first hot water system can meet the heating effect, the solar water heating system chooses the first hot water system to supply hot water, and when the first hot water system cannot meet the heating effect under rainy conditions, the solar water heating system can choose to be supplied with hot water by the second hot water system. In this way, energy consumption can be effectively saved and costs can be reduced.

[0053] It should be noted that when the first hot water system is selected to supply hot water, the heating work of the second hot water system can be carried out simultaneously, so that hot water that meets the use requirements can be provided in time when the supply of the first hot water system is insufficient. In addition, when the second hot water system is selected to supply hot water, if the first hot water system meets the heating effect, it can also be switched to the first hot water system to supply hot water to save energy consumption.

[0054] In some embodiments, the solar water heating installation system further includes a first temperature probe 11 and a control circuit. The first temperature probe 11 is disposed in the first insulated water tank 3, and is used to measure the temperature A of the water in the first insulated water tank 3. The control circuit is electrically connected to the first temperature probe 11, the first solenoid valve 9, and the second solenoid valve 10, respectively, and the control circuit is configured to: when the temperature A is less than the first temperature setting value, control the first solenoid valve 9 to close and the second solenoid valve 10 to open.

[0055] Specifically, under normal circumstances, the solar water heating installation system can choose the first hot water system to supply hot water, and when the first hot water system cannot meet the heating effect, the solar water heating installation system can automatically switch to the second hot water system to supply hot water. In this way, the automatic control of the solar water heating installation system can be realized, which can not only save labor but also improve the response speed compared with the manual operation method to ensure the reliable supply of hot water.

[0056] It should be understood that the first temperature setting value may be 35° C., 40° C., 45° C. or 50° C., etc. During specific settings, the operator may select a specific value according to actual conditions. This embodiment of the present application does not make any specific limitation on this.

[0057] In some embodiments, the solar water heating installation system further includes a second temperature probe 12. The second temperature probe 12 is disposed at the water outlet of the solar collector 7 and is used to measure the outlet water temperature B of the solar collector 7. The control circuit is electrically connected to the second temperature probe 12 and the first circulation pump 5, respectively, and the control circuit is further configured to control the first circulation pump 5 to be closed when the difference between the temperature B and the temperature A is less than the second temperature setting value.

[0058] Specifically, the difference between temperature B and temperature A can be used to determine whether the first hot water system can meet the required heating effect. Therefore, in a specific implementation, the operator can infer the difference between temperature B and temperature A based on the required heating effect, and use the difference as the second temperature setting value, so that the control circuit can control the first circulation pump 5 to be turned off when the difference between temperature B and temperature A is less than the second temperature setting value. In this way, when the first hot water system cannot meet the required heating effect, the relevant equipment can be turned off to reduce energy consumption.

[0059] It should be understood that the second temperature setting value may be 5°C, 6°C, 7°C, 8°C or 9°C, etc. During specific settings, the operator may select a specific value according to actual conditions. This embodiment of the present application does not make any specific limitation on this.

[0060] In some embodiments, the solar water heating installation system further includes a third temperature measuring probe 13. The third temperature measuring probe 13 is disposed in the second insulated water tank 4, and is used to measure the temperature C of the water in the second insulated water tank 4. The control circuit is electrically connected to the third temperature measuring probe 13, the second circulation pump 6 and the air source heat pump 8, respectively, and the control circuit is further configured to control the second circulation pump 6 and the air source heat pump 8 to be turned off when the temperature C is not less than the third temperature setting value.

[0061] Specifically, in the process of heating water or supplying hot water using the second hot water system, the second circulation pump 6 and the air source heat pump 8 can be turned on only when the temperature of the water in the second thermal insulation water tank 4 is lower than the threshold. Therefore, in the specific implementation, the operator can select an appropriate threshold as the third temperature setting value, so that the control circuit can control the second circulation pump 6 and the air source heat pump 8 to turn off when the temperature C is not less than the third temperature setting value. In this way, energy consumption can be reduced, especially in the period when the user does not use hot water for a long time.

[0062] It should be understood that the third temperature setting value may be 50° C., 55° C., 60° C. or 65° C., etc. During specific settings, the operator may select a specific value according to actual conditions. This embodiment of the present application does not make any specific limitation on this.

[0063] In some embodiments, the solar water heating installation system further comprises a first water supply pipe 14. The first water supply pipe 14 is connected to the first insulated water tank 3 and is used to supply cold water to the first insulated water tank 3.

[0064] Specifically, when the solar water heating installation system selects the first hot water system to supply hot water, as the user's hot water consumption increases, the amount of hot water in the first insulated water tank 3 will gradually decrease. Therefore, in order to ensure that the first hot water system can continuously supply hot water, in a specific implementation, cold water can be added to the first insulated water tank 3 through the first water supply pipe 14.

[0065] Further, the first water supply pipe 14 can be connected to the first insulated water tank 3 through the solar collector 7, that is, the first water supply pipe 14 is connected to the water inlet of the solar collector 7, so that cold water can be supplied to the first insulated water tank 3 through the solar collector 7. It should be understood that the lower the water temperature, the higher the heat exchange efficiency. Therefore, compared with the setting mode in which cold water first enters the first insulated water tank 3 and then enters the solar collector 7 for heat exchange, the cold water first passes through the solar collector 7 for heat exchange and then enters the first insulated water tank 3, which can effectively improve the heat exchange efficiency, thereby rapidly heating the water.

[0066] In some embodiments, the solar water heating installation system further includes a first water level meter 15 and a third solenoid valve 16. The first water level meter 15 is provided in the first insulated water tank 3, and is used to measure the water level D of the first insulated water tank 3. The third solenoid valve 16 is provided in the first water supply pipe 14, and is used to open / close the first water supply pipe 14. The control circuit is electrically connected to the first water level meter 15 and the third solenoid valve 16, respectively, and the control circuit is further configured to control the third solenoid valve 16 to open when the water level D is less than the first water level setting value.

[0067] Specifically, when the solar water heating installation system selects the first hot water system to supply hot water, the water level of the first insulated water tank 3 can be monitored by the first water level meter 15, so that the control circuit can control the third solenoid valve 16 to open when the water level of the first insulated water tank 3 is less than the first water level setting value, thereby realizing automatic water replenishment of the first insulated water tank 3. In this way, workers can be saved and the response speed can be improved.

[0068] It should be understood that the first water level setting value may be 1m, 2m, 3m, 4m or 5m, etc. During specific settings, the operator may select a specific value according to actual conditions. This embodiment of the present application does not make specific limitations on this.

[0069] In some embodiments, the solar water heating installation system further comprises a second water supply pipe 17. The second water supply pipe 17 is connected to the second insulated water tank 4 and is used to supply cold water to the second insulated water tank 4.

[0070] Specifically, when the solar water heating installation system selects the second hot water system to supply hot water, as the user's hot water consumption increases, the amount of hot water in the second insulated water tank 4 will gradually decrease. Therefore, in order to ensure that the second hot water system can continuously supply hot water, in a specific implementation, cold water can be added to the second insulated water tank 4 through the second water supply pipe 17.

[0071] In some embodiments, the solar water heating installation system further includes a second water level meter 18 and a fourth solenoid valve 19. The second water level meter 18 is provided on the second insulated water tank 4, and is used to measure the water level E of the second insulated water tank 4. The fourth solenoid valve 19 is provided on the second water supply pipe 17, and is used to open / close the second water supply pipe 17. The control circuit is electrically connected to the second water level meter 18 and the fourth solenoid valve 19, respectively, and the control circuit is further configured to: when the water level E is less than the second water level setting value, control the fourth solenoid valve 19 to open.

[0072] Specifically, when the solar water heating installation system selects the second hot water system to supply hot water, the water level of the second insulated water tank 4 can be monitored by the second water level meter 18, so that the control circuit can control the fourth solenoid valve 19 to open when the water level of the second insulated water tank 4 is less than the second water level setting value, thereby realizing automatic water replenishment of the second insulated water tank 4. In this way, workers can be saved and the response speed can be improved.

[0073] It should be understood that the second water level setting value may be 1m, 2m, 3m, 4m or 5m, etc. In the specific setting, the operator may select a specific value according to the actual situation. In this regard, the embodiment of the present application does not make specific limitations.

[0074] In some embodiments, the solar water heating installation system further includes a hot water supply pipe 20 and a hot water return pipe 21. The hot water supply pipe 20 is respectively connected to the hot water outlet of the first insulated water tank 3 and the hot water outlet of the second insulated water tank 4, and is used to deliver the hot water in the first insulated water tank 3 / the second insulated water tank 4 to the water-using end. The hot water return pipe 21 is connected to the hot water inlet of the second insulated water tank 4, and is used to return the hot water refluxed from the water-using end to the second insulated water tank 4 when the first solenoid valve 9 is closed and the second solenoid valve 10 is opened.

[0075] Specifically, in actual use, there is always hot water in the water-using end pipe. However, due to heat loss in the water-using end pipe, the temperature of the hot water in the water-using end pipe will continue to slowly decrease. Therefore, by providing the hot water return pipe 21, a hot water circulation can be formed between the second thermal insulation water tank 4 and the water-using end, so that the water in the water-using end pipe can be kept at a high temperature.

[0076] It should be understood that the first hot water system is unstable due to the influence of weather and other factors, because it uses solar energy to achieve heating. Therefore, a hot water circulation can be formed only between the second insulated water tank 4 and the water end, and the hot water return pipe 21 can be connected only to the second insulated water tank 4.

[0077] In some embodiments, the solar water heating installation system further includes a fifth solenoid valve 22. The fifth solenoid valve 22 is disposed in the hot water return pipe 21 and is used to open / close the hot water return pipe 21. The control circuit is electrically connected to the fifth solenoid valve 22, and the control circuit is further configured to control the fifth solenoid valve 22 to open when the first solenoid valve 9 is closed and the second solenoid valve 10 is opened.

[0078] Specifically, since hot water circulation is formed only between the second insulated water tank 4 and the water-using end, the fifth solenoid valve 22 can be set to control the fifth solenoid valve 22 to open when the solar water heating installation system selects the second hot water system to supply hot water. In this way, the hot water in the first insulated water tank 3 can be prevented from flowing back to the second insulated water tank 4.

[0079] In some embodiments, the solar water heating installation system further includes a fourth temperature measuring probe 23. The fourth temperature measuring probe 23 is disposed in the hot water return pipe 21 and is located upstream of the fifth solenoid valve 22, and is used to measure the return water temperature F of the hot water return pipe 21. The control circuit is electrically connected to the fourth temperature measuring probe 23, and the control circuit is further configured to control the fifth solenoid valve 22 to open when the temperature F is less than the fourth temperature setting value.

[0080] Specifically, in order to deliver hot water to the water-using end, a power device (such as the third circulating pump 24) should be provided on the hot water supply pipe 20. However, when the fifth solenoid valve 22 is opened, the water supply pressure will be reduced. Therefore, the opening time of the fifth solenoid valve 22 can be appropriately controlled to avoid pressure changes when using water. Specifically, in this embodiment, the return water temperature of the hot water return pipe 21 is monitored by the fourth temperature measuring probe 23, so that the control circuit controls the fifth solenoid valve 22 to open when the return water temperature is less than the fourth temperature setting value. In other words, the fifth solenoid valve 22 can be opened only when the hot water temperature at the water-using end does not meet the use requirements, so that the pressure changes when using water can be avoided as much as possible.

[0081] It should be understood that the fourth temperature setting value may be 35° C., 40° C., 45° C. or 50° C., etc. During specific settings, the operator may select a specific value according to actual conditions. This embodiment of the present application does not make any specific limitation on this.

[0082] One or more embodiments of this specification are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification should be included in the scope of protection of this application.

[0083] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
